Magnitude of force experienced by the electron and direction of force

  1. Aug 5, 2013 #1
    An infinitely long straight conductor 'XY' is carrying a current of 5 Ampere. An electron moving with a speed of 10^5 m/s parallel to the conductor in air from A to B. Calculate the magnitude of force experienced by the electron and direction of force.

    Pls help. Ur help will be greatly appreciated.

    I think you will need to know the geometry of the conductor and the distance the electron is from the conductor.

    Can you tell us what principles and equations apply here?

    You don't need any geometrical info on the wire, just the distance from the electron to the wire's center.

    (The electron is specifically moving in air, not the conductor).

    It doesn't say that the conductor is a wire. What if it is a flat plate? The magnetic field is not uniform around the plate. So just knowing the distance from the centre is not enough.

    Do you know any equations that enable you to calculate the force on a charge in a magnetic field?
    Do you know how to calculate the magnetic field due to a current in a conductor?

    That problem would be too difficult for an introductory course. I'm sure axial symmetry is implied.
    Also, the conductor is described as "XY", again suggesting an infinitely thin wire.
